Blaze Elemental

Whenever a land enters the battlefield under
your control, Blaze Elemental gets +2/+0 until
end of turn.
Whenever Blaze Elemental deals combat damage
to a player, you may sacrifice a land. If you do,
Blaze Elemental deals damage equal to the
sacrificed land's converted mana cost to any
target.
The fire within is as wild as the land beneath it.
